What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H436GKC100 — With Shunt | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This genuine OEM single-pole 30-amp contactor (part 1172472) is the switching relay that powers the compressor and condenser fan on the Tempstar T4H436GKC100. When the thermostat calls for cooling, the 24V coil pulls the contactor in, closing the high-voltage contacts and energizing the outdoor unit. This contactor includes a built-in shunt. Contactors are high-wear components — the contacts arc and pit every time they open and close, and over thousands of cycles they burn, weld, or chatter. A failing contactor causes hard starts, buzzing, or a condenser that won't run at all.
